I think it's a misuse of json.RawMessage.
what do you expect the output to be for the first marshal call?
{"tasks":[{"creds":null}]} is not the correct answer.

Can you explain why? I'd expect similar output to |
|
The content of RawMessage is the raw json data,
so it's impossible for a RawMessage to be nil or []byte{}.
Think how you can parse a valid json into a RawMessage
so that it's nil or []byte{}.

Then why does the last example run fine? There should be some consistency, at the very least. json.Marshal(json.RawMessage(nil))Outputs |
|
That's because the MarshalJSON method of json.RawMessage
is defined on a pointer receiver, so if you pass a json.RawMessage
to Marshal, it will be treated the same as a []byte and not as
a RawMessage.

I'd expect all three outputs to be sane json. There should be no errors here.
